Detailed procedures when installing cement pipes
Cement pipe drainage is often used in municipal engineering in our city. It is often used as a drainage pipe for rainwater and domestic sewage in the city. If there is no cement pipe, the road will be filled with rainwater and life falling from the sky. Sewage, we will live in a sea of water, there is no place to stay, so it plays a very important role in urban construction, there is no substitute. When installing cement pipes, we must carefully construct according to detailed procedures and plans.
Before the device is installed, all required measurement data must be measured-the more precise the better. According to the drawings, the center line, straight line, and curve are measured with the problem of 10 meters and 5 meters respectively, and the groove depth and slope are calculated.
Trench excavation is mainly excavator excavation, supplemented by manual bottom cleaning, and rainwater bucket connecting pipe and branch pipe are excavated manually. During the excavation process, pay attention to investigate the change of soil quality, and use support and support for road sections with landslide marks.
The height of the soil on one side of the groove is not more than 2 meters, and the distance from the edge of the groove is not less than 1 meter. For the maintenance of underground pipelines in trench construction, the relevant departments are required to make the pipeline bottom to clarify the fundamental orientation of the underground equipment. If necessary, excavate sample holes first to find out the accurate orientation, facilitate the construction, and ensure the safety of various buried pipelines. During construction, support and maintenance measures are selected for exposed pipelines.
Water discharge test must be done at the end of the device connection construction. Carefully investigate for a period of time to see if there is water leakage or leakage, and fix the problem in time. At the same time, when installing the cement pipe, we must also pay attention to some terrain problems to avoid the formation of the backflow phenomenon of the cement pipe during drainage, so that we will have a better effect when we use the cement pipe for drainage.
